Title: Process for the thermochemical-thermal treatment of hardened steels, heat-treatable steels and bearing steels
Inventor: WENZEL BINA DIPL ING
IPC: C21D1/78
Filed: 1993-08-14
Abstract: The invention relates to a process for the thermochemical-thermal treatment of hardened steels, heat-treatable steels and bearing steels, in which a surface zone of a workpiece, in particular tappets, roller bearing parts, gear box and clutch elements, is enriched with carbon and nitrogen and subsequently subjected to martensitic hardening. The process of the invention is characterised in that a carbonitridation (1) is carried out at a temperature of from 780 to 1050 DEG C with carbon enrichment and nitrogen enrichment of the surface zone from 0.4 to 1.2 per cent by weight of carbon and from 0.1 to 0.8 per cent by weight of nitrogen with a hold time of from about 1 to 4 hours, the carbonitridation is followed by quenching (2) to a temperature significantly below the martensitic start temperature of the surface zone, then there is carried out an annealing process (3) at a temperature above a nitrocarburation temperature at a heating rate of up to 50 DEG C per minute and a hold time of from about 1 to 2 hours and a cooling process (4) to room temperature, followed further by machining of the workpieces which is finally followed by a nitrocarburation (6) at a temperature of from 400 to 620 DEG C with a hold time of from 60 to 300 minutes and a cooling process (7) to room temperature. The process of the invention gives the material high wear resistance and load-bearing capacity even under very high tribological stresses.   <IMAGE>

Title: Flow-deflecting fairing part
Inventor: FEICHTIGER DIETER DIPL ING
IPC: B62D35/00
Filed: 1993-11-08
Abstract: It is known to attach a pneumatically actuable elastomer hollow profile, on which a flow-deflecting limb is formed, to that side of the shell of a fairing part which faces the flow, it being possible for the flow-deflecting limb to pivot into a swung-out or swung-in position by the hollow channel in the elastomer hollow profile being exposed either to positive pressure or negative pressure. In the case of the novel, flow-deflecting fairing part (1) provision is made for the elastomer hollow profile (3) to be arranged in such a manner on that side of the shell (2) of the fairing part which faces away from the flow that the deformation zone in a head region (24) of the elastomer hollow profile, which deformation zone is required for the pivoting of the formed-on flow-deflecting limb (7), remains covered on the side facing the flow (12) by an associated portion of the shell (2) of the fairing part. This measure prevents damage to the comparatively soft deformation region and prevents the bending and buckling lines formed there from being visible from the outside. Use, for example, for the rear spoiler arrangement of a motor vehicle. <IMAGE>

Inventor: KOEHLER WOLFGANG
IPC: F01K23/10
Filed: 1994-03-17
Abstract: The invention concerns a method and device for solar steam generation. A medium is conveyed through pipes (1*), which are disposed in solar collectors (1), and from there it is guided to a turbine (3) after heating and evaporation. A medium whose enthalpy is greater than that of saturated water relative to the pressure in the pipe (1*) is fed, initially by a feed line (5, 5*, 5**), into said pipe (1*) in the solar collectors (1). In addition, the pressure of the medium to be fed in is greater than the pressure in the pipe (1*). The medium to be fed in can be high-pressure water or high-pressure steam. For this purpose, the feed line (5, 5*, 5**), for example, can emerge from a water-steam separator (9) or a high-pressure turbine (32) forming part of a power station.
